#### Configure taosAdapter

Method to configure taosAdapter to receive StatsD data:

- Enable the configuration item in the taosAdapter configuration file (default location /etc/taos/taosadapter.toml)

    ```toml
    # Automatically create the database when writing data with the schemaless feature if set to true.
    smlAutoCreateDB = true
    [statsd]
    enable = true
    port = 6044
    db = "statsd"
    user = "root"
    password = "taosdata"
    worker = 10
    gatherInterval = "5s"
    protocol = "udp"
    maxTCPConnections = 250
    tcpKeepAlive = false
    allowPendingMessages = 50000
    deleteCounters = true
    deleteGauges = true
    deleteSets = true
    deleteTimings = true
    ```

    The default database name written by taosAdapter is `statsd`, but you can also modify the db item in the taosAdapter configuration file to specify a different name. Fill in the user and password with the actual TDengine configuration values. After modifying the configuration file, taosAdapter needs to be restarted.

    The `smlAutoCreateDB` configuration item is used to enable the automatic database creation feature. When set to true, taosAdapter will automatically create the corresponding database upon receiving data if it does not already exist.

- You can also use taosAdapter command line arguments or set environment variables to enable the taosAdapter to receive StatsD data. For more details, please refer to the taosAdapter reference manual.

#### Configure StatsD

To use StatsD, download its [source code](https://github.com/statsd/statsd). Modify its configuration file according to the example file `exampleConfig.js` found in the root directory of the local source code download. Replace \<taosAdapter's host> with the domain name or IP address of the server running taosAdapter, and \<port for StatsD> with the port that taosAdapter uses to receive StatsD data (default is 6044).

```text
Add to the backends section "./backends/repeater"
Add to the repeater section { host:'<taosAdapter's host>', port: <port for StatsD>}
```

Example configuration file:

```js
{
port: 8125
, backends: ["./backends/repeater"]
, repeater: [{ host: '127.0.0.1', port: 6044}]
}
```

After adding the following content, start StatsD (assuming the configuration file is modified to config.js).

```shell
npm install
node stats.js config.js &
```
